COMPOSITE LAMP- -CHIMNEY.

SPECIFICATION forming part of Letters Patent No. 506,734, dated. October 17, 1893.

Application filed April 20, 1893. Serial No. 471,237. (No model.)

To all whom it may concern:

Be it known that I, JACOB SCHWARTZ, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented certain new and useful Improvements-in Composite Lamp-Chimneys, of which the following is a specification:

According to my invention, I provide an attachment of an improved construction for lamp chimneys, adapted to prevent insects from falling into the chimney, and to prevent the flame from rising above the top of the chimney.

In the accompanying drawings illustrating my invention,Figure 1 is a perspective view of a lamp with my improvements applied.

Fig. 2 is a perspective view of the attachment.

The cylinder A is made of wire gauze, or other reticulated material, and at the bottom is provided with a perforated sheet metal ring 0. At the top it is provided with an imperforate cap or cover a, to which is secured a ring I), that may be attached by means of achain or other device to the frame of the lamp. The length of the cylinder is preferably about twice its diameter, the ring 0 being of proper interior diameter to fit the chimney to which the cylinder is to be applied. The chimney preferably extends a short distance into the cylinder, and may be made to partially or wholly support it, but I preferably suspend the cylinder from the lamp frame as indicated in Fig. 1.

I claim as my invention- The combination with a lamp chimney, of a perforated or reticulated cylinder having a perforated annular sheet metal bottom 0, and an imperforate cap a provided with devices attaching it to the lamp frame, substantially as described.
